However, deciphering MTF charts and comparing the resolution of different lenses can be a science unto itself. This tutorial gives an overview of the fundamental concepts and terms used for assessing lens quality.
27 sie 2014 · Some 'film' lenses designed for 35mm rangefinder cameras have a rear element which lies quite close to the plane of the film or sensor (mostly wide-angle lenses). These work fine for film, but when used on a digital camera cause quite noticeable colour shifts to the left and right of the frame.
6 maj 2024 · For full-frame digital cameras, lenses with focal lengths of 70–80mm or more are generally recommended, as they offer a good mix of image uniformity and practical working distance.
DXOMARK's comprehensive camera lens test result database allows you to browse and select lenses for comparison based on their characteristics, brand, price, lens type, lens size, focal range and aperture.
The higher a camera's resolution, the larger prints can be made while still retaining sharp details. There are two main factors that determine resolution: the film size or digital sensor size/megapixels, and the optical sharpness of the lenses used.
26 lut 2007 · Lp/mm is most appropriate for film cameras, where formats are relatively fixed (i.e., 35mm full frame = 24x36mm), but cycles/pixel (c/p) or line widths per picture height (LW/PH) may be more appropriate for digital cameras, which have a wide variety of sensor sizes.
Use 2.5 mm charts for compact digital cameras (11 mm diagonal sensors or smaller). 5 mm charts require longer camera-to-target distance, d 1. In practice you'll see little response above 100 lp/mm with film or digital SLRs.
